No tests for drag-and-drop functionality #3182
Description
Tests for drag-and-drop functionality have been implemented around 20 years ago, but were disabled during the E4 transition in 2012 via disabling the according test suite (b0b57f0), and they were never reenabled even after the test suite was used again (328d2f9).
Since the tests were not run for 13 years and became technically and functionally outdated, those tests have finally been removed via:
Still, tests for the drag-and-drop functionality would be useful, so this issue is a reminder to add such tests. The tests removed with the above mentioned PR might be a good indicator for what functionality could be relevant to test (and to a certain degree maybe also for how to do it).
